I'm having a problem starting up my Toshiba Satellite (A105-S4074).
The computer developed this problem suddenly. When I press the power button, the power status lights turns on, the fan starts, the CD-ROM starts (and continues to spin), the wireless light turns on, the keyboard lights flash, the hard drive light turns on for about 1 second and the hard drive is definitely spinning.
However, the screen doesn't turn on and the computer doesn't boot. After reading around a few threads I saw a bizarre recommendation to press down on the keyboard while starting it. I thought it was crazy but I tried it for fun... and it works! If I push down on the keyboard fairly hard and hold it, the computer boots every time. If I take off the pressure before Windows finishes booting the computer freezes.
After that, I realized that the computer also boots if I hold it upside down until it loads to the desktop.
After booting, however, I'm having problems with the computer freezing.
Any idea what might be loose that is causing this behavior? I'd like to tighten it down and have a fully functional computer again!

Not shuttingdown the laptop properly could mess the system. If Try to shutdown the laptop everytime your not going to use it and if it still didn't work you do a system recovery. After you're done doing the system recovery, make it habit to shutdown your laptop.

Thank you Ron.
However, my problem is that the laptop won't start unless I hold it upside down or press my hand against the keyboard. I don't think that would be caused by letting the computer hibernate.

While I agree that properly shutting down your system from time to time can help keep things in order, I don't think that has anything to do with this problem. There are 2 separate things going on.
When you power on the computer, all the circuitry gets fired up and has to seek an operating system to boot from. So the BIOS has to kick in to search for a bootable location and an operating system. Then once it recognises the hard drive, it can proceed loading the operating system stored there (which I believe is what is affected by a proper shut-down)
It sounds to me like the problem is in the circuitry firing up correctly and getting the BIOS started. Having it affected by the pressing down on the keyboard makes it sound like it's entirely hardware and not BIOS. Unfortunately I don't know exactly what it would be, so can't solve that problem conclusively, but wanted to clear up that it's probably got nothing to do with the operating system.
I would recommend getting inside and having a look, and while you're at it giving it a good clean with compressed air. Sometimes a bad connection is easily identifiable. Also, if any dust has accumulated in there, it could be allowing other paths for current to travel, thus incorrectly transmitting electric signals between components.
That's my thoughts. I have 2 Satellites that have had similar startup issues, and that's what I'm about to do with them.
I also found this thread that talks about power settings to the processor that might be worth a try. It may not apply to you because of the keyboard pressing situation:
